Application October 5, 1953, Serial No. 384,289

2 Claims. (Cl. 280--35) which can be moved to inoperative position lyingclosely adjacent the suitcase.

A further object of this invention is to provide a baggage dolly havingmeans for securing the same to a suitcase or the like, which means isadjustable to accommodate pieces of luggage of various sizes.

A further object of this invention is to provide a baggage dolly havinga leg supporting a wheel, which leg is extensible so as to position thepiece of baggage supported by the dolly at a convenient height for theuser.

A still further object of the invention is to provide a baggage dollywhich is simple and eflicient in construction and durable and lasting inuse.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view showing the baggage dolly forming thesubject of this invention attached to a piece of luggage;

Figure 2 is a sectional view taken substantially along section line 2--2of Figure 3;

Figure 3 is a view partly in section of the leg for supporting the pieceof luggage;

Figure 4 is a sectional view showing the leg in collapsed position;

Figure 5 is a perspective view of the baggage dolly forming the subjectof this invention; and

Figure 6 is a sectional view taken substantially along section line 66of Figure 5.

Referring now more specifically to the accompanying drawings, it will beseen that the improved baggage dolly forming the subject of thisinvention includes, as shown in Figure l, a base 10 having a strap 12secured thereto and adapted to be extended around a piece of luggage 14.

As seen in Figures 5 and 6, the base 10 consists of a horizontal,rectangular plate member 16 having a pair of T-shaped plate members 18secured one at each end thereof. The T-shaped members 18 are positionedwith the head portion thereof in a vertical direction and with the bodyportion thereof extending in a horizontal relation parallel to the plate16. The upper edge of each T-shaped member 18 is provided with anaperture 20 which receives an end of the strap 12 for securing the sameto the base 10. Each of the T-shaped members 18 is provided with aplurality of longitudinal slots 22 in the body portion thereof. Aplurality of bolts 24 extend through the ends of the member 16 andthrough the slots 22. Thus, the width of the base 10 can be adjusted byloosening the bolts 24 and sliding the T-shaped members 18 away fromeach other. By tightening the bolts after such an adjustment, theT-shaped members 18 will be locked in fixed position.

The member 16 is provided with a pair of spaced downwardly extendingcars 26 secured thereto adjacent the midpoint thereof. A hollowlongitudinal member 28 is pivotally secured between the cars 26 by meansof a pin .30. The member 28 is adapted to move in a direction transverseto the longitudinal axis of the member 16. A longitudinal member 32 ofless diameter than the internal diameter of the member 28 is slidablyreceived within the free end of the member 28. The member 28 is providedwith a plurality of transverse apertures 34 spaced along the lengththereof. The member 32 is provided with an aperture 36 adjacent the endthereof which is inserted in the member 28. A threaded pin 38 is adaptedto be inserted through a selected one of the apertures 34 and theaperture 36 for retaining the member 32 in fixed position with relationto the member 28. A nut body 40 engages on the end of the pin 38 toretain the same in position. Thus, the length of the leg can be adjustedby removing the pin and sliding the member 32 inwardly or outwardly inthe member 28 and then repositioning the pin 38 through alignedapertures.

The lower end of the member 32 is bifurcated, as at 42. A wheel 44 isdisposed in the bifurcation and is rotatably mounted thereon.

Means are provided for retaining the leg in extended position. Thismeans comprises a first member 46 hingedly secured at one end to themember 16 and with the pivotal connection thereof being spaced from thepivotal connection of the member 28 to the member 16. The member 48 ispivotally secured to the other end of the member 46 and also to themember 28. The hinge connection between the members 46 and 48 isdisposed on the sides of the members 46 and 48 away from the pivotalconnection of the member 28 to the member 16. Thus, the hinge connectionwill prevent the members 46 and 48 from moving in a direction away fromthe pivotal connection of member 28 to the plate 16 after the members 46and 48 have become axially aligned.

The member 16 is provided with a spring clip 50 secured adjacent oneedge thereof and extending downwardly therefrom. The spring clip 50 issubstantially U-shaped and is positioned in alignment with the pivotalconnection of the member 46 to the member 16 and the pivotal connectionof the member 28 to the member 16. Thus, when the leg is collapsed, themember 28 will be received between the prongs of the spring clip 50 andbe retained therein.

In practical use, the width of the base 10 is first adjusted toaccommodate the desired piece of luggage. Then, the strap 12 is securedaround the piece of luggage. Then, the leg is adjusted by sliding member32 within the member 28 to achieve the desired height. When it isdesired to transport the piece of luggage, the leg is placed in extendedposition. The wheel 44 is in contact with the ground and rolls thereonas the piece of luggage is moved. When it is desired to store theluggage, the leg is swung to inoperative position with the member 28being retained by the spring clip 50. In this position, the dolly willrest upon the ground on the lower edges of the head portion of theT-shaped members 18.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described,

and accordingly, all suitable modifications and equivalents may beresorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. In a baggage dolly, a base comprising a rectangular, horizontalbaggage supporting plate member, a pair of T-shaped plate membersslidably adjustably secured to the first named plate member at oppositeends of the first named plate member to vary the width of the base, saidT-shaped plate members having vertical head portions confining baggageon the first named plate member and providing ground engaging rests forelevating the first named plate member and baggage thereon ofi theground, a center leg for said base pivotally attached to the first namedplate member between the second named plate members for swinging intovertical and horizontal positions, respectively, to raise the base offthe ground and lower said head portions onto the ground, folding hingemeans pivoted to said first named plate member and leg, respectively,for unfolding by swinging of said leg into vertical position to holdsaid leg vertical and foldable by swinging of the leg into horizontalposition, and a terminal ground roller on said leg for rollablysupporting said base.

2. The combination of claim 1, and a baggage securing strap secured tothe upper edges of said head portions.
